[Sunil vignesh]

custom board not have 32.768khz crystal

 Have you tried setting the LFCLK source to RC?

Kind regards,

Håkon

Could you try creating this file in:

your-project/child_image/mcuboot.conf

 

containing this configuration as well?

 

Kind regards,

Håkon

I couldn't catch that

do you mean i need to create the folder child-image and bare mcuboot.conf file

what should be inside that .conf file

[Håkon Alseth]

This configuration shall be set in that child-image/mcuboot.conf file:

https://github.com/nrfconnect/sdk-zephyr/blob/master/drivers/clock_control/Kconfig.nrf#L33

 

Kind regards,

Håkon

debug doesn't start

1.

2.

[Håkon Alseth]

My deepest apologies, it should be "child_image" not "child-image".

 

Kind regards,

Håkon

[Sunil vignesh]

ok, No issue i'll try it. Thank you

[Sunil vignesh]

I have confg

# Clock configuration
CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

in prj.conf

and also in child_mage\mcuboot.conf

config_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

but when i check configure nrf connect

for menuconfig

but when i see mcuboot config

how to change it in .config file

[Sunil vignesh]

and when i change this in configure menu

i got this error

[Sunil vignesh]

Hi Håkon,

i have

disable the two stage low frequency clock

changed to synthesized from HFCLK

it works

but i need to config in .conf

how to do it

the mcuboot.conf changes doesn't work can you help for it

[Håkon Alseth]

It seems that mcuboot tries to use temp sensor for calibration intervals. We will need to disable this specifically for mcuboot. Could you try this in mcuboot.conf? 

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0
CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_TEMP_DIFF=0

 

Kind regards,

Håkon
